# Behold, the Sideways Elevator

Elevator company ThyssenKrupp has developed a "sideways elevator" known as MULTI. In many respects it's similar to a standard elevator—it's a car that's designed to move people between floors in buildings. But this elevator has two key engineering differences. First, it uses motors on tracks to move the cars, rather than a cable pulling the cars up and down. Second, the tracks themselves can rotate or be built in orientations that aren't just up and down. That last bit is what makes this so interesting.

In a conventional elevator setup, architects devote a columnar portion of the building to elevator shafts. Those are then outfitted with cabling and motors to move the elevator cars up and down between floors. There's plenty of fancy math engineers build in to optimize the availability and speed of those elevators. But typically, the biggest limitation is that for each elevator shaft, there is just one elevator car. (There are multi-car-per-shaft elevators known as "twin elevators," but the cars generally block one another in the shaft.)

MULTI allows multiple cars per shaft, with the ability to scoot cars sideways as needed, or even to build a zig-zagging shaft structure. This allows cars to get out of the way of each other, enabling all kinds of interesting algorithmic changes. The system could put multiple cars near high-traffic areas—and those areas might change based on time of day or other factors. Priority cars might be able to zip along, while others moved to the side to wait. A car might move sideways and enter another shaft, if that would create a faster path. Or imagine a dual-tower building—it could have a sideways elevator shaft (or many of them) to connect the towers. Imagine the time savings in traveling between upper floors of the two buildings, when such a linkage exists! As a broad concept, MULTI basically removes the idea of the elevator "shaft" and replaces it with something more like lanes on a road—and adds the ability to move along two axes rather than just one.

In the video below, Tom Scott visits a ThyssenKrupp testing tower to learn how it works. (He also makes it clear this is not sponsored content—it's a genuinely fascinating bit of engineering. It does seem the company is doing its public relations homework, though, as the first functional unit went online on June 22, 2017 in Rottweil, Germany.)

Behold:

If video isn't your thing, read up on the technology. While it will be many years before this kind of technology becomes commonplace, you may be able to tell your kids: "In my day, elevators only went up and down!"

# Ninja’s Hot & Cold Brewed System Is the Only Coffee Maker You’ll Ever Need

Amazon

Update: The glass-carafe version of the Ninja Hot & Cold Brewed System is currently on sale for \$99 (a 50 percent discount) on Amazon and Walmart. That's the cheapest price we've ever seen, so grab it while you can. The thermal-carafe version is on sale on Amazon for \$168, a 27 percent discount.

For people who just want a cup of joe to help them get out the door in the morning, the French presses, Chemexes, Aeropresses, Moka pots, and other specialized devices that coffee aficionados swear by probably seem more overwhelming than appealing. Ditto the fancy cappuccino machines at local cafes. That’s where Ninja’s new Hot & Cold Brewed System comes in: It was created to give coffee addicts a myriad of options with minimal fuss, not to mention minimal equipment. And it makes tea, too!

“Coffeehouses are known for having an endless selection, but current at-home brewers haven't given users the vast variety of choice we thought possible, and certainly not all in one product," Mark Rosenzweig, CEO of SharkNinja, said in a press release. "The Ninja Hot & Cold Brewed System changes the category entirely. This innovative system is more than just a machine you use in the morning; it's your all-day brewing partner.”

The Hot & Cold Brewed System comes with two baskets: one for coffee and one for tea. It knows what you're making to make based on the basket you insert, and the available options for that basket will light up. The machine allows the user to make six different sizes of coffee or tea, from a single cup all the way up to a full 50-ounce (10-cup) carafe.

And of course, as the name suggests, the system can make both hot and iced beverages. For coffee, it has five brew options: classic, rich, over ice, cold brew, and specialty (a concentrated brew for milky drinks like cappuccinos). If you’re making tea, you can choose between hot and cold brews optimized for herbal, black, oolong, white, or green tea.

When you select an over ice or cold brew, the machine automatically doubles the strength of your beverage so it doesn't get overly diluted by the ice cubes in the carafe. Even better, the Ninja can make cold brew in just 10 to 15 minutes, whereas other systems and methods typically take hours. (Hot coffee is brewed at 205°F, while the cold brew is made at 101°F.) And the system has a hot and cold frother that folds into the side so you can make barista-level lattes, too.

These bells and whistles sound impressive on paper, but how do they perform in real life? Ninja sent me Hot & Cold Brewed System to test for myself.

## Ease of Use

Though it might look like something developed by NASA, the Hot & Cold Brewed System is designed to easily work with the twist of a dial and the push of a button, and it delivers. From loading in the correct amount of grounds with the system’s “smart scoop” to picking what type of brew you’d like, it’s simple enough to use even while bleary-eyed in the morning. It’s also easy to schedule a delayed brew so you can do the rest of your morning routine while your coffee brews. (Here’s the only drawback I can think of about this machine: When it starts brewing, it’s kind of noisy—loud enough to make my cats jump. It’s not a dealbreaker, but if you live in a small apartment and plan to brew coffee so that it’s ready right when you wake up, it might be something to consider.)

The system even tells you when it needs to be descaled. The “clean” button will light up, at which point you simply fill the water reservoir with descaling solution and water and press the clean button. A countdown lets you know how much longer the clean cycle will last.

## Taste and Flavor

I swapped out an old, cheap coffee maker for the Hot & Cold Brewed System, and the difference was immediately noticeable. Whether hot or cold, the coffee made by the H&CBS was a better, smoother cup of joe. That’s due to what Ninja has dubbed Thermal Flavor Extraction automated brewing technology, which, according to a press release, “knows the precise temperatures, correct bloom times, and proper levels of saturation for every possible beverage combination to ensure a great taste every time.”

Whatever tech they use, it works. The coffee I make in this machine is consistently tasty. The rich brew setting works exactly as advertised, too, providing a richer, bolder flavor than the classic brew.

## Features and Accessories

One of the best things about the H&CBS is the fact that it cuts down on waste significantly. Unlike other machines, it doesn't require any plastic pods or paper filters. Instead, it comes with two permanent filters, one for coffee and one for tea.

And the cold brew function is a game changer if you prefer iced coffee to hot. Not only does it brew quickly, but it eliminates the messy cleanup that comes with making cold brew yourself.

Typically priced at \$230 for the thermal carafe version (or \$200 for the glass carafe), the Hot & Cold Brewed System is significantly more expensive than a simpler drip coffee machine. But if you’re a cold brew addict looking to treat yourself, it’s worth it. Consider springing for the slightly more expensive thermal carafe model, which will keep your java hot or cold for hours. (I’ve left ice in it overnight and found cubes the next morning.)

You can get the Hot & Cold Brewed System on Amazon, Walmart, Macy's, or directly on Ninja’s website starting at \$160.

# AT&T Is Now Blocking Robocalls by Default, a First for Cell Phone Providers

Nothing gets under the skin quite like robocalls, those irritating and persistent attempts to sell questionable services and perpetuate moneymaking scams. A recent Federal Communications Commission (FCC) ruling finally paved the way for cell phone carriers to block the calls by default, rather than requiring consumers to opt into a blocking service to stop them.

Now, AT&T is doing exactly that. But if consumers want to block all robocalls, they’ll still have to pay a little extra.

AT&T just announced an expansion of its Call Protect service that will automatically block robocalls suspected to be fraudulent free of charge. Users are also free to manually block individual numbers of known spam callers. But if a consumer wants to automatically block all robocalls, even those from legitimate businesses, it will cost an additional \$4 a month.

Call Protect was previously an opt-in feature: Users had to change their phone settings in order to take advantage of it. Due to the FCC ruling, AT&T can now activate Call Protect on all phones.

The benefit is expected to be available to all new AT&T service sign-ups, with existing users added in the coming months. If you don’t want to wait, you can download Call Protect as an app or turn it on via your AT&T account.

While AT&T is the first carrier to make the blocking feature a default, other cell phone providers offer similar functionality. T-Mobile’s Scam Block service blocks likely spam calls, while Verizon’s Call Filter and Sprint’s Premium Caller ID apps perform essentially the same function.

It’s expected robocalls will continue to face an uphill battle in an effort to reach consumers. The FCC also mandated that providers verify calls at the network level before reaching the consumer using a framework known as SHAKEN/STIR, or Signature-based Handling of Asserted Information Using toKENs and the Secure Telephone Identity Revisited standard. Clunky? Maybe. But the standard allows for carriers to catch suspected spam or fraud calls before they reach the consumer. All cell phone providers must implement it before the end of the year.

While nothing is likely to ever completely eliminate robocalls, at least we're making progress.
